沙特阿拉伯采购需求：数字牙科口内传感器，hdr-500/600

I am currently experiencing an issue with one of our sensors that seems to be non-functional. It appears to be prompting for a code that I do not have. This situation is causing some delays in our operations, and I'm eager to resolve it as soon as possible. Could you please provide guidance on how to proceed? Specifically, I'm looking for information on obtaining the necessary code or any troubleshooting steps that may help to get the sensor up and running again. Additionally, if there are any replacement options or support services available, I would appreciate those details as well. Thank you for your assistance!
